Could someone check my PayPal Smart Button? - button

Question

I'd be grateful if some kind person would glance over this PayPal SmartButton code?
I've put in the NO_SHIPPING and I'm not sure about all the brackets (){}[] and whether there should be double " or single ' inverted commas etc.
I'm OK with html, but this scripting mystifies me.
Thanks in anticipation, Steve

onApprove: function(data, actions) {
return actions.order.capture().then(function(orderData) {
// Full available details
console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
// Show a success message within this page, e.g.
const element = document.getElementById('paypal-button-container');
element.innerHTML = '';
element.innerHTML = '<h3>Thank you for your payment!</h3>';
//actions.redirect('https://www.website.com/');
});
},
onError: function(err) {
console.log(err);
}

Script SDK line is not correct, has extra spacing and a missing hyphen. You need:
<script src="https://www.paypal.com/sdk/js?client-id=sb&enable-funding=venmo&currency=GBP" data-sdk-integration-source="button-factory"></script>
That's simply the code the button factory would have generated for you, and it works.
For future reference most HTML/JS problems can be troubleshooted in a browser's Developer Tools, on the Console and Network and (for HTML) Inspect tabs, reloading the page once the Network tab is open for example.
